‘Sub-Earth’ exoplanet discovered around the closest solo star to us
Astronomers have discovered a planet orbiting the closest solo star to the solar system, known as Barnard's star. The newly discovered exoplanet has around half the mass of Venus, which classifies it as a "sub-Earth." The exoplanet, designated Barnard b, takes just over three Earth days to orbit its red dwarf parent star, which is located

Extreme exoplanet has a complex and exotic atmosphere
An international team including researchers from the University of Bern and the University of Geneva as well as the National Centre of Competence in Research (NCCR) PlanetS analyzed the atmosphere of one of the most extreme known planets in great detail. The results from this hot, Jupiter-like planet that was first characterized with the help…
Distorted exoplanet has the shape of a rugby ball
11.01.2022 Ein Jahr am Planeten WASP 103-b dauert weniger als ein Erdtag. Der riesige Planet hat dadurch eine ganz eigenartige Form. Im Sternbild Herkules umkreist der Planet WASP-103b sehr nah und in weniger als einem Tag seinen Mutterstern. Dadurch sind die Gezeitenkräfte auf dem Exoplaneten außerordentlich stark - und verformen ihn zu einem Rugbyball. Diese…
